Angular Contact Ball Bearings

The single-row angular contact ball bearing was designed to support radial, axial or composite loads, however, the axial load must be in one direction. The high thrust capacity is achieved by a higher shoulder on one side of the outer ring. The direction of the load through the balls forms the contact angle. The thrust capacity increases with the contact angle. The BMU bearings are commonly referred to as thrust bearings. These bearings have a 40 deg contact angle to accept heavy axial loads. The bearings have Universally Flush Ground rings to facilitate mounting in multiple bearing sets. The inner and outer rings have identical widths. These bearings can be mounted as DB, DF and DT pairs or can be combined into triplex and quadraplex sets. When two bearings are mounted together, a clearance or preload may be obtained without the use of shims or spacers. This bearing has a machined brass cage and is not available with seals or shields. These bearings are most commonly used in vertical pump and motor applications.

The single-row angular contact ball bearing was designed to support radial, axial or composite loads, however, the axial load must be in one direction. The high thrust capacity is achieved by a higher shoulder on one side of the outer ring. A matching high shoulder is often on the opposite side of the inner ring as well. The direction of the load through the balls forms the contact angle. The thrust capacity increases with the contact angle. This ball bearing has a 40 deg contact angle. This bearing has a stamped steel cage and is not available with seals or shields. These bearings are non-separable. These bearings have normal tolerances and are not suitable for mounting adjacent to each other to achieve a preload.

A double-row angular contact ball bearing is basically two single-row angular contact ball bearings with 20 deg contact angles, mounted back-to-back while contained within a narrower single bearing. These bearings occupy less axial space and can take a bi-directional axial, radial and moment loads in one bearing where it takes a matched pair otherwise.

Due to having contact angles, the Angular Contact Ball Bearing is suitable for applications demanding high accuracy and high rotational speed and is capable of withstanding combined radial and axial loads.
